2 Pig finishing farm industry finishing farm Weaning 10 weeks of age ± 25 kg Slaughter 28 weeks of age ± 110 kg

3 SEIR Model for HEV in pigs susceptible Experimental data (Bouwknegt et al. 2007): Transmission parameter: 0.66 infections per day per infectious animal Latent period: 3 (0.8 – 6.3) days Infectious period: 25.8 (7.0 – 54) days latently infected infectiousrecovered

4 Age distribution at high transmission weeks of age age at entryage at slaughter proportion of population R 0 = 17 susceptible latently infected infectious recovered total

5 Age distribution at lower transmission weeks of age age at entryage at slaughter proportion of population R 0 = 2.6 susceptible latently infected infectious recovered total

6 Infection dynamics at high transmission time (days) time of infection number of animals susceptible latently infected infectious recovered total R 0 = 17

7 Infection dynamics at lower transmission time (days) time of infection number of animals susceptible latently infected infectious recovered total R 0 = 2.6

8 Infectious period distribution infectious period (days) uncensored censored
